We are now getting to more and more recent drafts, which means there will be less and less big league players because a lot of these draftees are still very young today. Not everyone can break into the bigs at 19-years-old like Harper or 20-years-old like Mike Trout.
Nonetheless, the Giants got their man in Joe Panik with the 29th overall pick and his name is enough said. After just his second season, Panik is already an All Star and World Series champion. San Francisco got another steal in the Second Round in the name of Andrew Susac.
Although none of the following would be that much of an upgrade, we all saw how much of an impact Terrance Gore can have on a contending team like the Kansas City Royals in both 2014 and 2015.
Players Passed On:
OF Jackie Bradley Jr. (1st Round supplemental–40th)
